我需要在页面的侧边栏上包含一个php日历。
我使用的是几周前发现的一个片段，就像我以前使用过的一样，效果很好。但这一次，我必须添加下一个和上一个按钮来显示上个月或下个月。。。
我的问题是…我需要修改生成当前月份的php吗？
这就是我目前所拥有的：
<table class="month">
<tr class="days">
<td>Mon</td>
<td>Tues</td>
<td>Wed</td>
<td>Thurs</td>
<td>Fri</td>
<td>Sat</td>
<td>Sun</td>
</tr>
<?php
$today = date("d"); // Current day
$month = date("m"); // Current month
$year = date("Y"); // Current year
$days = cal_days_in_month(CAL_GREGORIAN,$month,$year); // Days in current month
$lastmonth = date("t", mktime(0,0,0,$month-1,1,$year)); // Days in previous month
$start = date("N", mktime(0,0,0,$month,1,$year)); // Starting day of current month
$finish = date("N", mktime(0,0,0,$month,$days,$year)); // Finishing day of current month
$laststart = $start - 1; // Days of previous month in calander
$counter = 1;
$nextMonthCounter = 1;
if($start > 5){ $rows = 6; }else {$rows = 5; }
for($i = 1; $i <= $rows; $i++){
echo '<tr class="week">';
for($x = 1; $x <= 7; $x++){
if(($counter - $start) < 0){
$date = (($lastmonth - $laststart) + $counter);
$class = 'class="blur"';
}else if(($counter - $start) >= $days){
$date = ($nextMonthCounter);
$nextMonthCounter++;
$class = 'class="blur"';
}else {
$date = ($counter - $start + 1);
if($today == $counter - $start + 1){
$class = 'class="today"';
}
}
echo '<td '.$class.'><span class="dayWrap">'. $date . '</span></td>';
$counter++;
$class = '';
}
echo '</tr>';
}
?>
</table>
<div class="changeMonthLinks">
<a class="col-xs-12" href="">< Prev</a>
<a class="col-xs-12 aright" href="">Next ></a>
</div>
我只是不知道该怎么办。。。或者我需要在锚标签中添加什么：S
任何帮助都将不胜感激。
谢谢非常感谢。
我现在已经为参数添加了$？现在在url中，我用strtotime将其解析为变量$dtNow，所有的日期函数都被扩展，底部的链接都用？now=$dtNow+1个月后？now=$dtNow-月
这是代码
<?php
$now = '';
if(isset($_GET['now']))
$now = $_GET['now'];
$dtNow = strtotime($now);
if(!$dtNow)
{
$dtNow = time();
}
echo "<h1>Today is " . date('Y-m-d', $dtNow) . "</h1>";
?>
<table class="month">
<tr class="days">
<td>Mon</td>
<td>Tues</td>
<td>Wed</td>
<td>Thurs</td>
<td>Fri</td>
<td>Sat</td>
<td>Sun</td>
</tr>
<?php
$today = date("d", $dtNow); // Current day
$month = date("m", $dtNow); // Current month
$year = date("Y", $dtNow); // Current year
$days = cal_days_in_month(CAL_GREGORIAN,$month,$year); // Days in current month
$lastmonth = date("t", mktime(0,0,0,$month-1,1,$year)); // Days in previous month
$start = date("N", mktime(0,0,0,$month,1,$year)); // Starting day of current month
$finish = date("N", mktime(0,0,0,$month,$days,$year)); // Finishing day of current month
$laststart = $start - 1; // Days of previous month in calander
$counter = 1;
$nextMonthCounter = 1;
if($start > 5){ $rows = 6; }else {$rows = 5; }
for($i = 1; $i <= $rows; $i++){
echo '<tr class="week">';
for($x = 1; $x <= 7; $x++){
if(($counter - $start) < 0){
$date = (($lastmonth - $laststart) + $counter);
$class = 'class="blur"';
}else if(($counter - $start) >= $days){
$date = ($nextMonthCounter);
$nextMonthCounter++;
$class = 'class="blur"';
}else {
$date = ($counter - $start + 1);
if($today == $counter - $start + 1){
$class = 'class="today"';
}
}
echo '<td '.$class.'><span class="dayWrap">'. $date . '</span></td>';
$counter++;
$class = '';
}
echo '</tr>';
}
?>
</table>
<div class="changeMonthLinks">
<a class="col-xs-12" href="?now=<?php echo date('Y-m-d', $dtNow - 30*24*60*60); ?>">< Prev</a>
<a class="col-xs-12 aright" href="?now=<?php echo date('Y-m-d', $dtNow + 30*24*60*60); ?>">Next ></a>
